OSHA-Its-the-law osha_valve
The OSHA Safety Standard Regulation 29CFR CHXVII Paragraph 1926.302(b)(7) states:   All hoses exceeding 1/2-inch inside diameter shall have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.

Prevent dangerous air hose whips and accidents.   Protect your most important assets: Your employees and their equipment.   OSHA COMPRESSED AIR SAFETY SHUT-OFF VALVES offers simple but efficient protection to pneumatic systems in the event of a broken compressed air hose or pipe.

Another OSHA guideline publication states:  “Hoses, cables, and other equipment shall be kept clear of passageways, ladders and stairs.” 

OSHA says reduce your slips, trips and falls. Slips, trips and falls constitute the majority of general industry accidents, which cause 15% of all accidental deaths, and are second only to motor vehicles as a cause of fatalities. The OSHA standard for walking and working surfaces apply to all permanent places of employment, except where only domestic, mining, or agricultural work is

Consider adding reels to increase safety & efficiency with your electrical cords, welding cables, air hose, oil, grease, liquid/water or fuel hoses.  This could be one of your most effective equipment additions you’ll ever make…as well as one of the safest!

Here are 5 Reasons to use Hose Reels:

  1. Increase Efficiency Hose reels makes all your hose handling more efficient. An organized, clean workplace is proven to be more efficient.
  2. Provide a Safer Work Environment Hose reels decrease you chances of injuries from tripping hazards.  Reduce accidents and insurance expense:  Slips, trips and falls are the leading cause of work stoppage in industry. Reels can help you meet OSHA Safety Requirements.
  3. Protects Equipment Hoses (and cords) last five times longer when stored on a reel. This can save you from replacing hoses as often. Keep hose off the floor where it can be damaged by trucks, doors, and dropped tools.
  4. Stop Leakages Hoses on reels can reduce the threat of expensive leakages of air and any fluids carried through your hoses.
  5. Increase Productivity Locating your hoses quickly- when and where you need them- can increase productivity.  All these factors help improve your work environment, which saves you time, equipment and money. ____________________________________________________________

Reels are suitable for many applications – such as industrial, automotive, marine, chemical, welding, petroleum, food processing, aviation, and electrical.

Reels are used to transfer air, water, motor oil, transmission fluid, grease, gear oil, anti-freeze, diesel fuels, welding gases, fuel oil, liquid pesticides, fertilizers, detergents, hydraulic oils, cutting oils, printing inks, solvents, chemicals, and blacktop sealers.

Probably one of the largest uses of hose reels is for Compressed Air. Compressed air is clean, readily available, and simple to use. As a result, compressed air is often chosen for applications for which other energy sources are more economical.  Inappropriate uses of compressed air include any application that can be done more effectively or more efficiently by a method other than compressed air.

Don’t WASTE your Compressed Air. Check your facility for wasteful and perhaps even unsafe uses of compressed air. Bottom Line:   Invest in durable, quality reels that make hoses, cords and cables more productive, keep them easily accessible and make them last longer.

The most used, most needed and most valuable Compressed Air Formulas

Do you have access to the most used, most needed and most valuable Compressed Air Formulas? Here’s one of the most used formulas you should keep on hand…
How to find how many CFM your air compressor delivers.

Follow these steps to find out how many
CFM Your Air Compressor actually delivers

1. STOP the compressor unit

2. CLOSE the outlet valve on the tank/air receiver

3. DRAIN the condensate from air receiver until there is 0 PSIG -then close the drain valve

4. NOTE THE TIME– in minutes & seconds (Best to write it down.) Then START THE UNIT.
When the compressor unit stops and unloads – then NOTE THE TIME again – in minutes & seconds. Convert the minutes into seconds and then total the number of seconds it takes between START and STOP/UNLOAD.

5. NOTE the GUAGE PSIG reading

6. NOTE the Air Receiver/Tank GALLON SIZE


TANK GALLONS x .536* x PSIG divided by SECONDS

*.536 is a formula factor for the unknown that works to give you the CFM delivery.

You have an 80 gallon tank, your total start to stop/unload time was 3 minutes and 9 seconds.
Change the minutes to seconds timed (60 x 3= 180 seconds plus 9 seconds totals 189).  You will use the total number of seconds189 and the noted 175 PSIG within the formula as shown below:

80 multiplied by .536 = 42.88
42.88 multiplied by 175 (example PSIG) = 7504.00
7504.00 divided by 189 (total seconds)= 39.70 CFM delivered

You now know that your air compressor is delivering 39.70 CFM

Your Response to this evaluation should be to compare this number with what your air compressor manufacturer says your CFM should be and evaluate how efficiently your compressor is running.


Compressor Terms you should know:

Cubic Feet Per Minute (cfm) – Volumetric air flow rate.

“psig” means pounds per square inch, GAGE pressure. Gage pressure is the absolute pressure of something, with the atmospheric pressure subtracted. In practice, when someone gives a pressure in just “psi” they probably mean gage pressure. If they mean absolute, they should be using “psia.”

Gauge Pressure – The pressure determined by most instruments and gauges, usually expressed in psig. Barometric pressure must be considered to obtain true or absolute pressure

Load Time – Time period from when a compressor loads until it unloads.

Unload – (No load) Compressor operation in which no air is delivered due to the intake being closed or modified not to allow inlet air to be trapped.

Receiver – A vessel or tank used for storage of gas under pressure. In a large compressed air system there may be primary and secondary receivers.

Demand – Flow of air at specific conditions required at a point or by the overall facility.

Figuring the correct pipe size for your compressed air distribution system is an important task. 
Pipe that is sized too small can create big pressure losses and reduce operating efficiency. Replacing piping is costly.  On average, 70% of a contracted piping job goes for labor and 30% for materials.

Do you know the biggest mistakes made in figuring compressed air piping sizes?
Many people who plan the piping never consider the fittings or the future.

Every pipe fitting creates a certain amount of increased frictional air loss that is equal to a specified length of pipe.
For every 100 feet of pipe you will have a ONE POUND PRESSURE DROP caused by frictional air loss.
Any turns in the pipe at fittings, ells, tees, and valves increase pressure drops even more.  That’s why the EQUIVALENT LENGTH OF PIPE (FT.) for PIPE FITTINGS chart was developed to help you determine the best pipe size for your system.

Are you planning to add more equipment in the next year or two?  Then plan for larger piping now.  Since the material costs in piping are low compared to installation or replacement cost, it’s wise to select pipe of an adequate size. If there is any doubt that a pipe size may create a pressure drop, use the next largest size. Remember that an oversize pipe compensates for possible scale build-up and provides for future expansion of the overall air system.

Steps to figuring what size piping your compressed air system needs:

  1. Determine your air compressor’s maximum CFM.
  2. Draw a piping schematic and show all pipe fittings, valves, etc.
  3. Measure and write the corresponding lengths of pipe on your schematic, then total the length of all straight pipes needed and note that on your schematic.
  4. Using TABLE 1, find your compressor’s CFM number on the far left column,
    and then go to the right until you see the column header with nearest length in feet to your total pipe length. Find where the CFM & PIPE LENGTH intersect on the chart and it will show the recommended pipe size for that length.
  5. Take that pipe size to TABLE 2 and use the table to find all the EQUIVELENT LENGTHS OF PIPE needed for each PIPE FITTING.  Write these lengths on your piping schematic at each fitting.
  6. TOTAL all the EQUIVELENT LENGTHS OF PIPE needed for each PIPE FITTING and add to your total of straight length of pipe.  This will give you a new and more accurate total pipe length needed.
  7.  Take your new total of EQUIVELENT LENGTH OF PIPE IN FEET back to TABLE 1 and use this number to determine the PIPE SIZE you need.
  8. Think of the FUTURE!
    Now is the time to plan for larger piping that may needed for additional future equipment.
